What is a Super Heinz system?

A Super Heinz system consists of 120 bets which transpire from 7 picks. Twenty-one 2-pick multis (parlays), thirty-five 3-pick multis (parlays), thirty-five 4-pick multis (parlays), twenty-one 5-pick multis (parlays), seven 6-pick multis (parlays) and one 7-pick multi (parlay). At least two of the seven picks must be correct to gain some winnings - the exact amount of the winnings depends on how many of the predictions prove correct.
